  • Patent number: 5510583
    Abstract: A switch assembly having a rocker type actuator user moveable for actuating plural switches in a housing. The rocker type actuator includes first and second rocker members journalled together for rotation about a common axis. The first member has a paddle extending out of the housing and a first cam portion for actuating a first switch upon initial rotation in one direction. Upon continued rotation in the same direction, overtravel of the first switch is absorbed by a torsion spring which permits resiliently biased lost motion of the first cam with respect to a second cam for subsequent actuation of a second switch. The torsion spring provides a significant increase in the force required to move the actuator between the first and second switch actuation to provide tactiley discernable feedback to the user of the state of switch actuations.

  • Patent number: 4904831
    Abstract: An improved phased-array active antenna transmit-receive means utilizing a multiplicity of individual transmit-receive cells positioned in an array format upon a common wafer of semiconductor material. Each transmit-receiver cell, comprises a multiplicity of redundant, integrated circuit, electronic devices implanted upon the common semiconductor substrate. The transmit-receive cells utilize novel mitered mechanical switches to permanently interconnect individual electronic devices into either transmit or receive circuits during the fabrication and test of the transmit-receive cells. Radio frequency and direct current input and output vias formed from a novel metal evaporation technique connect the devices upon the surface of the common semiconductor wafer to underlying, insulated direct current distribution circuits and a radio frequency manifold.

  • Patent number: 4773089
    Abstract: A telephone line-switching device comprises first and second switches that interlock and a lock plate extending between the two switches. The push member of the first switch has a cam with which the lock plate usually engages. The push member of the second switch has an inclined portion on which the lock plate always bears. As the push member of the second switch is depressed, the inclined portion horizontally moves the lock plate, permitting the lock plate to disengage from the cam to release the first switch.

  • Patent number: 4670629
    Abstract: An alternate action push-push switch is disclosed, having a housing with a dielectric bar portion; a plurality of conductive terminals; a plurality of conductive spring contactors having an inclined segment in proximity to the dielectric bar portion and a contact segment in proximity to the terminal contact portion; at least one push member slideably disposed at least partially within the housing; an alternate action switch mechanism having a closed loop cam slot, a cam follower, and a resilient spring disposed between the housing and the push member, to provide unidirectional travel of the cam follower in the cam slot as the push member is alternately biased between first and second operating positions. More than one push member may be used to supply multiple switching configurations. A protrusion on a first push member may be adapted to actuate an adjoining second push member, while allowing the second push member to be operated independently of the first push member.

  • Patent number: 4145590
    Abstract: An electrical switch apparatus includes at least a pair of electrical switches and an actuating mechanism for sequentially actuating the switches. Each of the switches includes a push button which is movable between first and second positions, and the actuating mechanism includes an actuator which is movable between a first position, at least one intermediate position, and a third position. The actuator includes a cam for each of the push buttons. One of the cams is engageable with one of the push buttons to move the push button to its second position as the actuator moves to an intermediate position, and the other cam is engageable with the other push button to move the push button to its second position as the actuator moves to its third position.

  • Patent number: 4095123
    Abstract: A controller comprises a first and a second pushbutton each carrying a pair of actuator pins of different lengths, first and second normally open switches located below each of the actuator pins having a reduced length, and a first and a second normally closed switch located below each of the other actuator pins. When depressed, each pushbutton causes its pin of an increased length to actuate its associated switch initially and then causes the other pin to actuate its associated switch. When the first pushbutton is depressed, a first circuit including the first normally open switch and the second normally closed switch in series is completed, and when the second pushbutton is depressed, a second circuit including the first normally closed switch and the second normally open switch in series is completed. When neither pushbutton is depressed, the first and second normally open switches prevent either the first or the second circuit from being completed.
